The current situation of Tuzik branch in Tokuji is a canal, with the main problems being serious seepage, low drainage coefficient of canal system, irregular cross section, inefficient water conveyance and lack of overcurrent capacity; Not effective irrigation and other prominent issues. The design of the cross-section of its channel must be based on the geological survey results, the actual operation and management of the project to select, after a comparison, considering the construction operation management, construction costs and construction materials and other factors, the choice of structural forms of full-face cast-in-place concrete Plan board, anti-frostbite choose benzene board frost heaving program.
